My Classic VX 1600 with twin Webbers does not like going out when the sun is shining - which is great in the current weather. After 5 mins in traffic it just cuts out completely, the fan does not kick in so the engine is not running hot. The fuel pump will run and the engine will turn over (unless i flatten the battery) and It will not start at all for 10 or 15 mins when it suddenly respond to the starter. I have recently replaced the fuel pump as it was making a clatter but it has not made any difference. i am wondering if i am getting a vapor lock as it only happens when the engine is ticking over in traffic and not when I am blatting about. The battery is also knackered so that does not help with the restart but would that effect the fuel flow? Any thoughts much appreciated.
